GeForce GTX 770 SLI is a combination of 2 GeForce GTX 770 put together using NVIDIA's SLI technology. Together, this combination offers 3072 Shader Processing Units, 256 TMUs and 64 ROPs. This, on a 256-bit memory interface, per card, of fast GDDR5. While the central unit runs at 1046MHz and goes up to 1085MHz, in Turbo Mode, the memory clock operates at 1752MHz. Best case scenario, this combination performs better than dual-graphics GeForce GTX 690 but ultimately, its performance depends on the driver support and on the 3D application. Therefore, and paired with a powerful processor, all demanding games are playable at the highest settings. Still, this combination might surpass the 450W barrier of TDP and so it will require a very powerful PSU.

Would my i5-3470 bottleneck 770 sli? i know i need a new psu for this and mobo….but still. and if you can suggest any good psu that would be able to handle 770 sli and any lga 1155 mobo that is good and can support sli. thanks

would 660 sli really last that long? i could spring for 760 sli or would that not really make a difference? and if i were to switch to 1150 which cpe should i get(i dont really care about OC) and if i do switch to 1150 what sli ready mobo

i've money for 780ti sli. but i'll stick with my 650ti boost sli until gtx 800 series releases. the same thing i'm telling u to do. by doing this u will be more futureproof and have more powerful rig ;)

4570>(-6%)3470 and 4670>(-8%)4570. u said that u want to change mobo that's why i told u to buy 4th gen. though the difference wouldn't be much noticable but will be more futureproof and latest that 4670 is -15% powerful than 3470….

not a bit saw a 680gtx pcie comparision the card can to 100% on a pcie3x8 and 99% on a pcie2x8 if you go down to pcie3x4(like most cheap mobos do) you get 95% so x8 is recomended then you have 2 times x8 i dont think you cpu can handle 32 lanes also there is no differenz no 2x8lanes

With your CPU, motherboard, RAM, SSD (If any) and HDD your setup would take approximately 640 watts, I'd pick a 750 watts Corsair CS or anything alike since that's more than sufficient, 850 is a bit overkill.

I don't believe an i5 CPU would bottleneck SLI 770's to be frank, even though the best matchup's an i7. Though if it'd happen to be less than required you could make an attempt on OCing 10% or so (Just remember to switch from stock cooler)
